Don't forget that the name of Jared falls all through these Michael's. even Phillip Michael b 1800 in VA son of Phillip Michael and Mary Evans, who married Elizabeth had a son Jared Michael who married Lavinia Fox.
Also Casper Michael had a son Jared Michael who married Mary Kelso, also, judging from the land records, I believe that Jared Michael who married Ruth Shoemake is son of Phillip Michael and Mary Evans, so does one other researcher, but again like so many lines from Phillip and Mary it is unproven.
Also according to the 1820/1830/1840 Dearborn and Decatur Co., census, Phillip and Mary had 12 children, six boys and six girls, and these families tended to stay togeather in some of the moves to Illinois.
Even Jared Michael (son of Phillip Michael and Elizabeth)who married Lavinia Fox went to Clay Co., Illinois and had a son Phillip born there. Also many lines that seem to come from Phillip and Mary Michael have twins in them. Twins usually run every other generation. My Ruth Michael was married in Clay Co., Illinois and went back to Decatur Co., IN. They were married there during the time that her brother Jared and Lavinia were there.
My great great grandparents Ruth Michael and William Henry Voiles had twin girls in 1876 in Decatur Co., Indiana.
I do think that Casper Michael is also a son of Phillip and Mary.
